The security vulnerability that led the U.S. government to impose export controls on Anthropic’s Fable 5 and Mythos 5 models is a simple technique that involves just three simple words: Fix this code.That’s according to a detailed blog post from Katie Moussouris, the founder and CEO of Luta Security. Anthropic had asked Moussouris, who has held two government advisory roles on cybersecurity and previously worked as a cybersecurity expert at Microsoft, to review a report on the security vulnerability in its Fable model that cybersecurity researchers at Amazon had produced. The vulnerability, which was later reported to the Trump administration, including in a phone call Amazon CEO Andy Jassy had with the White House, led the U.S. government to impose export controls on Fable as well as the underlying base model, Mythos.Because U.S. export controls work in a way that distribution of the technology to any noncitizen is deemed to be an export, even if those individuals are physically located in the U.S., the company said it had no choice but to disable the two AI models for all users. The export controls would have meant that Anthropic’s own noncitizen employees would not be allowed to use or work on the models.

The jailbreak was easy, an independent researcher says. But she and other cyber experts say defenders need Fable and ask that the export ban be lifted.
